d7f3cfb56e bug #564: document the fact that minCoeff/maxCoeff members have undefined behavior if the matrix contains NaN. 2013-04-09 11:27:54 +02:00

5adcc6c7b4 Add support for NVCC5: most of the Core and part of LU are callable from CUDA code. 
Still a lot to do.

3e4a68cc60 optimize vectorized reductions by peeling the loop: 
- x2 for squaredNorm() on double
 - peeling the loop with a peeling factor of 4 leads to even better perf
   for large vectors (e.g., >64) but it makes more difficult to keep good performance on smaller ones.

bdd7c6c88a change the value of Dynamic to -1, since the index type is now configurable. 
remove EIGEN_ENUM_MIN/MAX, implement new macros instead

42a1c983c1 fix bug in sliced redux 2010-05-13 23:22:18 +02:00
Benoit Jacob
92da574ec2 * allow matrix dimensions to be 0 (also at compile time) and provide a specialization 
of ei_matrix_array for size 0
* adapt many xprs to have the right storage order, now that it matters
* add static assert on expressions to check that vector xprs
  have the righ storage order
* adapt ei_plain_matrix_type_(column|row)_major
* implement assignment of selfadjointview to matrix
  (was before failing to compile) and add nestedExpression() methods
* expand product_symm test
* in ei_gemv_selector, use the PlainObject type instead of a custom Matrix<...> type
* fix VectorBlock and Block mistakes

871698d3aa Introduced NestParentByRefBit and NestByRefBit - this should fix temporaries related to nested products. 
Fixed a few typos and a few warnings.

25f8adfa6c * Fix bug #79: ei_alignmentOffset was assuming that ptr is multiple of 
sizeof(Scalar), and that assumption breaks with double on linux x86-32.
* Rename ei_alignmentOffset to ei_first_aligned
* Rewrite its documentation and part of its body
* The variant taking a MatrixBase doesn't need a separate size argument.

5cb779e5e1 * introduce ei_alignmentOffset(MatrixBase&,Integer) 
couldnt put it in Memory.h as it needs the definition of MatrixBase
* make Redux use it

94c706d04f Assign.h: add LinearTraversal (non-vectorized index-based traversal) 
Rename some constants to make names match more closely what they mean.

6347b1db5b remove sentence "Eigen itself is part of the KDE project." 
it never made very precise sense. but now does it still make any?

8aa5aa269a add "slice vectorization" of redux (eg. m.block().minCoeff() is now 
vectorized)
 2009-03-09 23:16:39 +00:00
Gael Guennebaud
51c991af45 * exit Sum.h, exit Prod.h, welcome vectorization of redux() ! 
* add vectorization for minCoeff and maxCoeff
 2009-02-12 15:18:59 +00:00

42b237b83a * make sum and redux honor EvalBeforeNestingBit too 
* fix MSVC issues (hopefully)
 2009-01-28 21:09:08 +00:00

89f468671d * replace postfix ++ by prefix ++ wherever that makes sense in Eigen/ 
* fix some "unused variable" warnings in the tests; there remains a libstdc++ "deprecated"
warning which I haven't looked much into

8ea8b481de As discussed on ML: 
* remove the automatic resizing feature of operator =
 * add function Matrix::set() to be used when the previous
   behavior is wanted
 * the default constructor of dynamic-size matrices now
   creates a "null" matrix (data=0, rows = cols = 0)
   instead of a 1x1 matrix
 * fix UnixX typos ;)

7245c63067 Complete rewrite of partial reduction according to mailing list discussions. 2008-07-19 11:36:32 +00:00

dc9206cec5 split sum away from redux and vectorize it. 
(could come back to redux after it has been vectorized,
and could serve as a starting point for that)
also make the abs2 functor vectorizable (for real types).

fb4a151982 * more cleaning in Product 
* make Matrix2f (and similar) vectorized using linear path
* fix a couple of warnings and compilation issues with ICC and gcc 3.3/3.4
  (cannot get Transform compiles with gcc 3.3/3.4, see the FIXME)
 2008-06-19 23:00:51 +00:00

eb7b7b2cfc * remove Cross product expression: MatrixBase::cross() now returns a temporary 
which is even better optimized by the compiler.
* Quaternion no longer inherits MatrixBase. Instead it stores the coefficients
  using a Matrix<> and provides only relevant methods.

6998037930 * move some compile time "if" to their respective unroller (assign and dot) 
* fix a couple of compilation issues when unrolling is disabled
* reduce default unrolling limit to a more reasonable value

310f7aa096 moved purely "array" related stuff to a new module Array. 
This include:
 - cwise Pow,Sin,Cos,Exp...
 - cwise Greater and other comparison operators
 - .any(), .all() and partial reduction
 - random
